rotora, ur paying for the name pretty much. but piston size comes into play. so im not sure

friesm2000

iTrader: (4)

and the total pad area available

p.diddy

iTrader: (3)

yea thats the same thing i was thinking.

how much does the rl swap cost anyway?

friesm2000

iTrader: (4)

there is also the availablity of many different pad compounds with rotora, but the acura ones don't have too many choices, but you can still get more track-oriented ones from EBC

so kinda depends on your end goal for the car

Rajca

iTrader: (8)

and the pads are a whole lot cheaper to replace on the rl calipers than the rotora. ebc red stuff pads with the rl calipers is what im doing. i have the red stuff pads on my stock calipers and love them to death

p.diddy

iTrader: (3)

if the stopping power is bout the same i might do the RL route instead.

Rajca

iTrader: (8)

^that what im doing and getting them powdercoated. should cost me less than half of what rotora wants for their and u only get to chose between two colors on the rotora.

p.diddy

iTrader: (3)

if i do get the RL im going to powdercoat them SMR. damn if i can do the swap for less than half id be crazy to pay $1300 for rotora.

04-up RL, any model.

The price of the swap all depends on what rotors and pads you go with, and the biggest variable is the price of the calipers.

SS lines arent needed, but I recommend them. The rubber lines are at least 7 years old, and rubber deteriorates. Go with either Goodridge or Russell.

civicdrivr

iTrader: (9)

I doubt you can do it for half, but if you can

It will definately be cheaper though.

Well stop buying generic ebay crap and spend some money.

Stainless steel lines > OEM rubber lines, and they will last longer.

Research first then post, because when you talk you make it seems like you don't know what you are talking about.

Including the pads and fluid flush I have less than 650 into this. The calipers came with usable pads and the fluid was clean but I chose to do it.

The SS lines were also a choice, I got them on sale for 98.00 delivered. The Goodrich were out of stock but available for 10.00 more and the rep said the difference was indistinguishable (I was willing to wait for them, they would have made $ yet he said it was not necessary, there was no difference).

The pads can take up to 1k miles to fully seat yet the brakes feel much better. I am very happy with my results.

friesm2000

iTrader: (4)

so what are you doing to the rear now to help balnce out the bias???
and i would say even increase the rear bias over stock , due to less weight transfer from being lowered

e30cabrio

iTrader: (6)

Nothing. I already have Frozen slotted rotors back there which are bigger & thicker than OEM. The brakes are working great and I am not an engineer.

No BBK changes the MC or system bias. I have done this type of mod in countless cars, the only one I changed anything else on was my 325 (put a 750MC in that had a 5mm larger piston bore) which made no real difference.

friesm2000

iTrader: (4)

MC???

but yes it does, maybe not the pressures inside the system, but now your front brankes are more effective from the larger piston (not much really compared to stock, but still has a larger surface area) but the real thing that will upset the balance is the fact that you got an rotor that is over an inch larger the stock, so really you need less force to actually have it brake at the same force (on the front axle) as stock , which the back is still basically doing (the upgraded rotors do help some, but not enough to offset the more powerful fronts), let alone the rear can take more braking force just from the less weight transfer from being lowered

so if you really want to stop faster, the rears need to be upgraded more to balance the braking out more

e30cabrio

iTrader: (6)

Master Cylinder.

The breaks are working great. The MC sends the fluid to the ABS pump, the ABS system sends the pressure needed to the wheels as needed.

My primary interest and reason for this mod was to increase efficiency & the ability of the brakes to wick off heat. (that they look cool is a bonus) It gets hot here before the brakes are applied.

These components are larger & the calipers are aluminum both things that make cooling better.

I have no intention of messing with the logic/proportioning part of the system.

Rajca

iTrader: (8)

would the stock front calipers fit the rear with new brackets? only thing is finding a rotor. maybe we can use the stock rotor???

e30cabrio

iTrader: (6)

You need a rotor with the parking brake drum.

Rajca

iTrader: (8)

thats what im thinking also. just wondering if their was a easy way out.

e30cabrio

iTrader: (6)

I looked all over and decided to leave it alone before I did the swap. Now that I have had it for a few days it feels great and as the pads seat and the computer learns the changes it can only get better.

I am going to leave it alone.

Rajca

iTrader: (8)

alright. thx for the updates

friesm2000

iTrader: (4)

i know the 350z has the correct diameter for the parking brake (actually it is 1mm bigger, but should be able to make that up with adjustments), but the biggest thing i would say is i don't know if it is deep/wide enough for the drum's shoes, also the rotor might have the wrong offset too, but if it needs a bracket to move the caliper for the larger rotor, it should be no problem to recenter the caliper

friesm2000

iTrader: (4)

to also help change the bias of the system, you can also put more aggressive pads on the rears, with weaker pads up front, which will also change the balance too

Rajca

iTrader: (8)

hmm. my bro works at a nissan dealership so ill ask him if he can bring a rear rotor from a 350z.

e30cabrio

iTrader: (6)

Great idea! I really wanted to get a vented disk back there, could not find any.

friesm2000

iTrader: (4)

sweet......., but they proably won't have one of those rotors in stock though, but a used one would be no problem especially for just test fitting it, to see if it works

ps: also try to get one for the brembo brakes

Rajca

iTrader: (8)

haha, im gonna try to get a used/bad one. just for test fitting.

CL-S progression 01

iTrader: (2)

yea why the hell do we not have a rear vented disk brakes?

is the RL or new TL equipped with a vented rear?

kinda seems like we got chinced out large back there with that tiny rotor :-(

friesm2000

iTrader: (4)

because we got fwd, and most weight of fwd cars is over the front axle, so rear brakes don't have to be as big; aka they can get away with solid rotors
and i still prefer solid rotors over drums

the newest tl's, even the awd ones, i think are still solid. and the newest rl's i think do have vented
a big part for rear vented is the static weight distribition, and how much weight is on that axle

a bigger brake was not needed back there , even then they geneally seem to last through 1-2 sets of front brakes

CL-S progression 01

iTrader: (2)

i just compare it to my last car (probe) and the rears were same thickness basically and just the diameter of the rotor was a bit larger, and the calipers themselves are roughly the same also. (on the rear of the car).... front is a whole different story.

so 2900ibs vs 3450lbs equals my question.. but i get where ur coming from. It is overkill. but it should at least be an option i think imho

friesm2000

iTrader: (4)

stock wise i also think we got a pretty soft suspension, so more weight transfer happens when you brake (idk bought my car already lowered)

also it depends on the manufacture of how much front bias they actually want, with how much sooner the front will lockup before the rears do (so they can vary how hard it is to bring the back end around when stupid people do brake in the middle of a courner)

CL-S progression 01

iTrader: (2)

honestly I got just the rear sway bar and new moog links, and honsetly it's not bad. the sway is very minimal.

I got more than I expected for sure. So i opted not to buy the suspension, and hold out till something gives

but as for ur point relating to braking i gotcha. car leans front brakes do way more and rears become useless.

like a bicycle.

that looks sick!

07HR350Z

The 350z does not have slotted rotors stock from 03-08 including the nismo Z. I don't know about the 09 370z. As for the proportioning valve, I used to have a stoptech 14" BBK on my 07' 350z and it had a proportioning valve since I only purchased the front kit. This is to correct the brake bias. Trust me, if you install only the front kit it'll throw off your brake bias. If you call stoptech, rotora, or even brembo, they will tell you the same thing.



Here's a picture of the OEM 07 nismo rotor.

civicdrivr

iTrader: (9)

Believe me, I know that the brake bias is changed with the BBK. Ive installed larger brakes on other cars, and Ive upgraded from drums to discs on my Civic. But what do you suggest we use to adjust bias?

e30cabrio

iTrader: (6)

No one said the bias did not change, and no one said the slotted rotors were OEM.

I have larger than stock rear rotors and more aggressive pads which increase the stopping potential of the rears.

ABS is taking care of the rest.

The brakes work great.

Civic, I think your dog needs a dentist.
